comment There aren't any animals like hornets that hunt large prey (like a rabbit, or even up to a deer), right? Why not?
@Kal: Do you really think that a swarm of hornets would be undetectable to a rabbit? Remember, as well, that even if this strategy would work first it has to evolve and for that you need to have functional, beneficial, intermediate steps - what do you think they could be?

@Owen_R: The comparison between honey bees and hornets is moot; the comparison which is evolutionarily relevant is to investing their energy in hunting small prey as they do now. In order to start hunting large prey they need to get a benefit from ineffectually hunting these prey since they have not yet adapted to do it well.

comment Why and how does uniprot list ~150,000 proteins in the human genome?
The key point is that there are more proteins than genes because so many genes exist in multiple splice forms. You should not expect number of genes and number of proteins to match up.

comment Is there an advantage to antibacterial soap?
I'd note that less bacteria on your hands is not necessarily a good thing. The natural microbiome on your hands has noticeable protective effects.

comment Recessiveness of allele for protection of organism
Honestly, I think the whole concept of recessive and dominant is unhelpful when trying to understand genetics and we'd be better off teaching the concepts in this answer from the very start.

comment What is the point at which abiogenesis is complete and evolution begins?
Yeah, that's it. Although even then I'd be wary of assuming that there is a single clear line dividing life from non-life, so the exact end point of abiogenesis will be ill-defined.

comment Why are fruits so large compared to their seeds?
@MarchHo: Okay, fair point. What I mean is that it's not just that they have smaller seeds it's that these seeds are, as you say, totally non-viable.

comment Why are fruits so large compared to their seeds?
Just to note, the Cavendish banana, like all other edible bananas doesn't just have small seeds, it is seedless. In fact, all banana plants (of the same variety of banana) are genetic clones of one another produced by vegetative reproduction rather than sexual reproduction.

comment Does DNA have the equivalent of IF-statements, WHILE loops, or function calls? How about GOTO?
Even in parallel programming languages, each statement in executed sequentially. It's just that there are multiple "threads" of execution going at the same time. DNA is neither data nor program. The analogy is totally inaccurate.

I'm not saying that DNA needs proteins to execute its functions; I'm saying DNA is fundamentally unlike computer code.

While your examples are clever I feel the analogy used here (DNA against computer code) is so very poor as to be misleading.
